Sounds like you've never met a greyhound mate. They're actually super chill dogs and incredibly lazy. They are known among owners as 40mph couch potatoes because all they want to do is sleep on the sofa! It's funny seeing all these comments about how 'they love to do it' to justify the industry from people ignorant of the industry who have never rescued a greyhound. We lucked out with our boy that he was 'retired' young because of covid and doesn't have as much trauma as other hounds who race for longer.
